yeah :)

shorter but more readable:
for ARGUMENT in "${ARGUMENTS}"; do
        case "${ARGUMENT}" in
                --all) Clean_all ;;
                --cache) Clean_cache ;;
                --chroot) Clean_chroot ;;
                --binary) Clean_binary ;;
                --remove) Clean_remove ;;
                --purge) Clean_purge ;;
                --stage) Clean_stage ;;
                --source) Clean_source ;;
                *) "${0}" --usage ;;
        esac
done

btw, it doesn't resolve the issue ;)

i mean the bug still exist:
sudo lh_clean --purge
lh_clean: unrecognized option `--purge'

it seems related to Arguments function handling ...

cheers,
